Embodiment Construction

[0017] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0018] Such as figure 1 The shown cage 3 has a cage pocket 2 on it, and an oblique oil hole 1 is provided at the bottom of the cage pocket 2. The method for processing the oblique oil hole of a bearing entity cage according to the present invention mainly includes processed as figure 1 The shown oblique oil hole 1 comprises the following steps:

[0019] a: Manufacture of special drill guiding device (tooling): such as figure 2 , image 3 , Figure 5 The shown guiding device is composed of a circular platform 22, a rectangular boss 23, a draw-in groove 4, an oblique positioning hole 21, and a guiding drill sleeve 13. The round table 22 and the rectangular boss 23 are integrally formed. In the embodiment, the round table 22 is made of a copper rod of suitable size, and the rectangular boss 23 and the slot 4 are milled on a vertical machining center. The rectan...

Abstract

The invention discloses a proucting approach for oblique oil hole in bearing solid retainer, comprising the following steps: a: the making of special purpose device for drill guide: design a special purpose drill guide, which includes round platform, rectangular boss, draw-in groove, oblique location hole, guiding drill bushing; The processing of oblique location hole: determines the access site of oblique location hole on the special purpose drill, then conduct drilling processing after clamping tightly; The processing of guiding drill bushing: The guide bush is embedded in the oblique positioning hole in the guiding device , guide bushing and guide deviceInterference fit. b: The processing of the oblique oil hole: positioning the round platform diameter periphery of exclusive drill with pocket bore diameter arc surface, positioning groove bottom with retainer pocket bottom hole, and load each pocket hole of retainer one by one, processing inclined oil hole with manual and electric drills. The invention solves the problem of producing oblique oil hole of bearing retainer, reducing the processing cost and ensuring the design requirements of the product..

Description

technical field [0001] The invention belongs to the field of bearing cage processing, and mainly relates to a method for processing inclined oil holes of a bearing solid cage. Background technique [0002] The existing solid cage of a thrust cylindrical roller bearing is applied to the spindle bearing of a large CNC machine tool. By designing and processing the inclined oil hole at the bottom of the pocket hole of the brass cage, the lubricating oil circuit in the pocket hole is increased, and the cage and the cage are improved. The lubricating effect between the rollers and the raceways can take away a large amount of heat generated by the friction of the bearing during rotation, so that the spindle bearing of the CNC machine tool can be fully lubricated during work, preventing the bearing from overheating and failing, thereby improving the service life of the bearing. [0003] In the current market, EDM is commonly used to process inclined oil holes, which has low efficien...
